With the booming of telecommunication and microelectronics, it is essential to develop electromagnetic interference (EMI) shielding materials with low reflectivity characteristics avoid secondary pollution from waves (EMWs). Herein, we fabricated a series hierarchical polypyrrole/carbon nanofiber (PPy/CF) composites multilayer PPy films. The EMI performance can be adjusted by attaching different layered efficiency (SE) PPy/CF composite films reach 74.59 dB an electrical conductivity 3.02 ×...
Redox‐based diagnostic and therapeutic applications have long suffered from a shortage of suitable drugs probes high specificity. In the context anti‐ferroptosis research for neurological diseases, inaccessibility blood‐brain barrier permeable (BBB) small molecular ferroptosis inhibitor, lack specific seriously impeded deeper understanding mechanism development clinically applicable drugs. We here report novel 1,3,4‑thiadiazole‐functionalized drug‐like ferrostatin analogue entitled...
Impact loads can have major adverse effects on the safety of civil engineering structures, such as concrete-filled steel tubular (CFST) columns. The study mechanical behavior and stress analysis CFST columns under impact is very important to ensure their against loads. At present, internal monitoring concrete cores still a challenging subject. In this paper, PVDF (Polyvinylidene Fluoride) piezoelectric smart sensor was developed successfully applied core column consists film sandwiched...
W–Y–N coatings with yttrium content ranging from 0 to 8.2 at.-% were deposited by reactive magnetron sputtering technique. The influence of on the structure, oxidation resistance and mechanical properties was investigated. results show that atoms substitute tungsten forming solid solution coatings. All exhibit a single-phase face-centered cubic structure preferred orientation changes (200) (111) addition. grain size decreases increase content. temperature increases 500°C at Y 730°C Y. are in...
Tuned mass dampers (TMD) have been widely used in passive vibration control, but their main disadvantage is that the reduction effect may be greatly affected by natural frequency of structure. In order to solve this limitation, we designed a adjustable tuned damper (FATMD) based on magneto rheological elastomer (MRE), which new type smart material, with stiffness, obtained changing magnetic induction. We MRE change stiffness FATMD track However, adding TMD will system. Therefore, combined...
ABSTRACT A detailed tire-rolling model (185/75R14), using the implicit to explicit FEA solving strategy, was constructed provide a reliable, dynamic simulation with several modeling features, including mesh, material modeling, and strategy that could contribute consideration of serious numerical noises. High-quality hexahedral meshes tread blocks were obtained combined mapping method. The actual rubber distributing nonlinear, stress-strain relationship bilinear elastic reinforcement modeled...
Fluidelastic instability (FEI) is the most harmful vibration mechanism for heat exchangers. Due to inevitable manufacturing precision and assembly error, natural frequencies of tubes are not equal in ideal condition. In order describe dispersion characteristic tube bundles, a new factor named ratio proposed this paper. A series experiments normal square rotated triangular array with pitch s = 1.4 1.28 were designed conducted high-speed camera visual image processing system. Results show that...
A new piezoelectric composite, macro fiber composite (MFC) is recombined with piezoceramic fibers, an epoxy resin basal body, and interdigitated electrode. It has been widely applied in vibration reduction deformation control of thin-walled structures, due to its great deformability flexibility. Research on actuation performance mostly concentrated the MFC actuating force calculation based classical plate theory (CPT), overall modeling structure. However, they have some deficiencies tedious...
Compared to ordinary rotor, rod fastening rotor has the advantages of lighter weight, higher strength and easier installation, so it is widely used in gas turbine. However, process a long-term operation, may be deformed due influence alternating load, high temperature other uncertain factors. In serious cases, can even lead major accident. The discontinuous characteristic leads great differences dynamic characteristics compared rotor. Based on Herz contact theory GW model, effect between two...
This paper elaborated eco-building-materials and life cycle assessment, proposed to follow in the eco-design philosophy of construction, focuses on basic approach building materials eco, including ecology traditional high-tech research development eco-building materials. It pointed out urgency importance eco-building-materials.
High boron steel is prone to brittle failure due the boride distributed in it with net-like or fishbone morphology, which limit its applications. The Quenching and Partitioning (Q&P) heat treatment a promising process produce martensitic excellent mechanical properties, especially high toughness by increasing volume fraction of retained austensite (RA) matrix. In this work, Q&P used improve inherent defect insufficient steel, effect mechanism on microstructure transformation change...
The cyclic deformation behaviors of 42CrMo steel with different heat treatments were observed by uniaxial straining and stressing tests at room temperature. softening/ hardening features the tempered or annealed their effects on ratcheting produced in asymmetrical discussed. It is concluded that shows significantly softening feature, but one stabilizing. Different are also observed. For steel, a special tertiary behavior previous greatly accelerates evolution strain subsequent stressing. In...

Presently, most of the common placement methods actuators are based on structural response and system energy to select optimal locations. In these methods, contribution controllability seismic excitations each mode structure not considered, a large number cases need be calculated. To solve this problem, Clough–Penzien spectral model is combined with Luenberger observable normal form calculate state. The modal disturbance degree, considering controllability, defined by using gramian matrix...
